I don't know anything about valves, but I always thought of them as voltage controlled current output devices characterized by gm. Of course intuition is not always right. It could be that the typical circuit to get the things working and not melting and capacitive feedback from plate to grid might very well mean that the devices have a fairly narrow voltage gain. Any of that true?
